Specific embodiment
The embodiments of the present invention is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the utility model easily, it is clear that described embodiment is
The utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's every other embodiment obtained without making creative work belongs to the utility model protection
Range.
As shown in Figure 1, the utility model provides a kind of air supply system performance intelligent test device, including MCU processor
1, the inner surface of the test box 2 is arranged in test box 2, the MCU processor 1；The test box 2 includes cabinet 21, in institute
It stating cabinet 21 and is internally provided with one group of electric air pump 22, being connected in the bottom end of the cabinet 21 for will test air supply system
The test component of energy parameter is sent into the propulsion device 23 of safety valve on the air pipe line of air supply system.
The test device be intended to by manually use propulsion device 23 will test component be sent into safety valve in, carry out respectively with
Lower two tests:
First item test: the air pipe line internal performance parameter (air pressure, temperature etc.) of air supply system is tested.
Section 2 test: whether test safety valve meet the requirements or damage.
The test device can simultaneously test air pipe line and safety valve, not need to distinguish using different tools
It is detected, testing efficiency is high.
In the present embodiment, propulsion device 23 includes cylinder body 231, and electric air pump 22 includes aspiration pump 22a and inflator pump
The gas nozzle of 22b, aspiration pump 22a and inflator pump 22b are connected to the cavity 232 inside cylinder body 231 by snorkel 24, in cylinder body
Cavity 232 is divided to test cavity 232a and seal cavity 232b, sealing block 233 and cylinder body 231 by sealing block 233 in 231
Inner sidewall is in close contact, and is fixedly connected with part in the other end of sealing block 233 and is pierced by outside seal cavity 232b and for close
The reference test bar 234 of safety valve on envelope insertion air pipe line；Test air passage 235 is equipped in reference test bar 234, in the sealing block
The venthole 236 through the sealing block 233 is provided on 233, the test air passage 235 is connected to the venthole 236.
It in the present embodiment, is to be tightly connected between aspiration pump 22a and inflator pump 22b and cylinder body 231, specific mode
Can routinely in 231 top end opening of cylinder body and the measures (not shown) such as sealing valve is arranged.
Sealing between sealing block 233 and cylinder body 231 can be by using be integrally formed or gluing etc. in the way of realize it is close
Envelope.Likewise, can also routinely between reference test bar 234 and seal cavity 232 (being equal between the inner wall of cylinder body 231)
Sealing is realized using modes such as integrated molding or gluings.
When carrying out first item test (air pipe line test): aspiration pump 22a is connected with inflator pump 22b keeps cylinder body 231
Leakproofness but be failure to actuate, by 234 leakproofness of reference test bar insertion air pipe line on safety valve entrance, open the safety-valve,
The gas of air pipe line once passes through test air passage 235, venthole 236 enters test cavity 232a, by test cavity
The parameter of setting sensing element detection gas in 232a.Parameter includes air pressure, temperature etc..
Consideration further decreases error, and the volume of general cylinder body needs as less than normal as possible.Since the volume of cylinder body is fixed
, so, the faint error of cylinder body volume bring itself can obtain specific error amount, in this way in reality by many experiments
When border operates, so that it may make up error amount.So that test is more accurate.
When carrying out Section 2 test (safety valve testing), closed safe valve, by the insertion safety of 234 leakproofness of reference test bar
Valve obtains the air pressure born in safety valve, (this by test cavity 232a by inflator pump 22b to inflating in safety valve
When, entire test device can be equivalent to the effect of air pipe line), until air pressure inside reaches pressure value required for test
When, stop the work of inflator pump 22b, whether detection safety valve has gas leakage, after with aspiration pump by entire test device
It evacuates, until air pressure inside reaches negative pressure value required for test, stops the work of aspiration pump, judge the pressure of sensing element detection
Whether force value changes, to judge whether the gas outside safety valve is able to enter inside.
Leakage inspection mode can be answered with feel, or be detected beside safety valve with lousiness, paper.
In the present embodiment, it whether is able to enter internal test to safety valve extraneous gas, is mainly used for inciting somebody to action
Whether safety valve is placed under negative pressure state qualified, and on the other hand, a certain item performance parameter of safety valve equally will affect other
Performance, in the case of preventing long-time service, this performance can gradually be had an impact entire safety valve.
In the present embodiment, in order to more preferably realize that the data between sensing element and MCU processor are transmitted, by test chamber
Body 232a is in one end far from the reference test bar 234, that is, close to one end of MCU processor 1, on the top of test cavity 232a
End is provided with groove 26 for installing sensing element 25, be provided in groove 26 penetrate the cylinder body 231 for for institute
The string holes 27 that 25 data line of sensing element passes through is stated, is tightly connected between the sensing element 25 and the groove 26.
The sensor different with specific reference to actual test demand integration of sensing element 25, such as in this embodiment, emphasis
Integrated pressure sensor, temperature sensor, humidity sensor etc..
Between sensing element 25 and groove 26 sealing equally can routinely by the way of gluing.
Being tightly connected between reference test bar 234 and the sealing block 233 similarly can the side using gluing routinely
Formula or integrally formed mode.
The received data of MCU can be connected to the equipment such as computer by data line and be analyzed and processed.
In the present embodiment, the sealing performance being inserted into safety valve due to needing to consider reference test bar 234, so testing
The end of bar 234 is integrally formed with hollow test syringe needle 237, in the test syringe needle 237 and 234 end of reference test bar
Connecting portion is provided with sealing ring 238；The test in hollow channel and the reference test bar 234 in the test syringe needle 237 is logical
Air flue 235 is connected to.
Enter in safety valve in test syringe needle 237, sealing ring 238 can closely be connect with the entrance of safety valve, Neng Gougeng
Effectively reach sealing effect, sealing ring 238 is designed as cone angle towards the conical structure for testing 237 tip portion of syringe needle.
The test device of the utility model carries out test parameter by introducing the gas in air pipe line in cylinder body, and
Safety valve is inflated by inflator pump, test device is modeled to air pipe line, judges safety valve under the pressure value needed for testing
It is whether normal, therefore, it is determined that whether safety valve can work normally when air pipe line air pressure inside is excessive, easy to operate, test
It is high-efficient.
